as we know range of sin x =[ –1, 1]
so the range of f(x) = [3+ 2*( –1), 3+ 2*(1)]
= [1, 5]
hope it helps

-1 ≤ sinx ≤1Therefore, -2 ≤ sinx ≤ 2 (multiplying by 2 and since 2 is a no. No change will be there in the inequality) Now, Adding 3, we get; -2+3 ≤ 3+2sinx ≤ 2+3Therefore, 1 ≤ 3+2sinx ≤ 5Therefore, range will be [1, 5]
